Naval Architecture

Naval architecture is the field of engineering which deals with the
design, construction and repair of ships, boats, and other marine
vehicles. Ship and vessel design relies on many of the same technologies
and engineering expertise found on shore, but achieving safe and
effective operations at sea is the focus of a unique discipline.

Naval architecture is the familiar term for what is formally called
marine engineering involving basic and applied research, design,
development, design evaluation and calculations throughout the entire
lifespan of a vessel. Preliminary design of the vessel, its detailed
design, construction, trials, operation and maintenance, launching and
dry-docking are the responsibilities of the engineer.

The basis of the discipline can be found in Archimedes’ principle, which
states that the weight of a static floating body must equal the weight
of the volume of water displaced by the object. This law determines not
just the draft at which a vessel will float but also the angles that
will be formed when equilibrium with the water has been achieved. Basic
stages of ship design are focused on predicting the size of the ship
that the sum of all possible weights will mandate. To make these
predictions, a naval makes use of experience-based formulas that help
calculate the approximate values necessary. The engineer can refine
these figures to accurately predict the depth of water needed to float
the vessel.

Naval architects are also tasked with calculating the static and dynamic
stability of a given vessel, as well as the damage buoyancy and
stability. Ship design calculations are also required before undertaking
ship modifications, including conversion, rebuilding, modernization, and
repair. Naval architecture participates in the formulation of safety
regulations and damage control rules. Marine engineers are also involved
in the approval and certification of ship designs in order to fulfill
statutory and non-statutory requirements.

Zentech, Inc. has acquired the former Derrick Barge 23 and renamed it ZEE RIG 3. “We intend to upgrade the vessel in two phases, first for use as a crane barge with increased lifting capacity, and later as a much larger self-propelled jackup vessel for wind farm installation service,” said Zentech President Ramesh Maini. The vessel is being prepared for conversion work at a Gulf Coast shipyard.

The vessel was purchased from Bohen Crane and Equipment Repair LLC. In its current configuration, ZEE RIG 3 is 400 Ft. long, 100 Ft. wide and has a hull depth of 29 Ft. (121.9m long, 30.5m wide and 8.8m hull depth)
